The outrageous comedy/reality series stars British chameleon Sacha Baron Cohen, who travels across America in the guise of one of three totally different characters. Cohen's primary alter-ego is Ali G., who calls himself a hip-hop journalist , but who's really a white rapper-wannabe. When Cohen isn't putting Ali G and his guests in unusual and often delightfully uncomfortable situations, he's shedding his yellow gangsta track suit attire and slipping into two other memorable characters: Borat, an impossibly naive TV reporter from Kazakhstan, and Bruno, a gay, Austrian fashionista. Each of these characters will be traversing America, exploring different aspects of our culture, and interviewing real celebrities and dignitaries.
